Inertia yog cov cuab yeej ntawm pawg uas tiv thaiv kev hloov pauv. … Mass thiab tshaj tawm yog ob qho tib si ncaj qha proportional rau lub zog. Yog tias koj nce qhov hnyav lossis nrawm, lub zog ntawm cov khoom nce proportionally. Yog tias koj muab ob npaug rau qhov loj lossis nrawm koj muab ob npaug rau lub zog.
Puas yog lub zog nce ntxiv thaum khoom ntog?
Speed, Acceleration, Force, and Momentum
Qhov no acceleration ua rau cov khoom nce nyob rau hauv ceev los ntawm 9.8 meters ib ob txhua thib ob nws ntog nyob rau hauv lub ntiajteb txawj nqus. yog li khoom nce nrawm thoob plaws nws lub caij nplooj zeeg.
Puas lub zog hloov nrog kev nrawm?
Acceleration yog qhov hloov pauv nrawm dhau sijhawm. Ib yam khoom uas ua kom nrawm, yog li ntawd, muaj qhov nce nrawm thiab nce nrawm.
Puas qhov khoom nrawm dua muaj lub zog ntxiv?
Cov khoom loj muaj lub zog ntau dua rau qhov muab ceev, thaum cov khoom sib zog muaj lub zog tsawg dua. Ib yam li ntawd, cov khoom txav nrawm dua muaj lub zog ntau dua cov khoom txav qeeb. …
Puas lub zog muab cov khoom inertia?
Yog li, inertia piav txog ib qho khoom tiv thaiv kev hloov hauv kev txav (lossis tsis muaj zog), thiab lub zog piav qhia tias nws muaj zog npaum li cas. Pop quiz teb: Momentum yog koj lub zog lossis nrawm ntawm kev txav, tab sis inertia yog qhov ua rau koj mus. … Nws yog inertia cia nws tseem.

Ntxiv ntxiv ntxiv ntxiv lawm?
Ntxiv mus yog nce qib nce los ntawm ntxiv. Tsis tas li ntawd yog qhov yooj yim ntxiv, ntxiv yog ntxiv thiab ua kom muaj kev sib cav, qhov ntxiv yog ntxiv, nce kev sib cav, thiab qhia tias qhov laj thawj ntxiv yog qhov sib txawv dua li qhov laj thawj yav dhau los.
Lub sijhawm nce siab nce lub zog nqa yog?
nyob rau hauv kev nce siab, yog tag nrho upwards ntsug quab yuam los ntawm txhua qhov chaw (tis, tail, engines, fuselage) loj dua, lossis sib npaug ntawm qhov hnyav ntawm lub dav hlau. Nyob rau hauv ib tug ruaj khov nce, net ntsug quab yuam yuav tsum yog xoom, yog li net ntsug aerodynamic quab yuam yuav tsum sib npaug rau qhov hnyav.
Qhov twg hauv qab no txiav txim siab txog cov luag haujlwm ntawm cov neeg muag khoom / tus nqi qis thiab cov neeg yuav khoom / tus neeg xauj tsev?
